Recommendation on hosted intranet

[Here_to_learn]

I'm trying to find a god hosted intranet solution to use for knowledge sharing between a number on consultants. I have list of featured that I'd like to see:

Accessible from most browsers
Discussion forum, threaded
Ability to upload documents and files
Free text and keyword search
wiki-like functionality to collaborate around knowledge
email notifications on changes
login/password protectedThere are some other things I'd like to see also, but lets start there. If you happed to know of some site that can provide me with functionality like this, I'd be glad to here about it!

I have looked a little at http://www.jot.com/index.php and http://www.iceboxportal.com/ and they look promising, but I'd like to have more to look at and choose from.

Check out phpbb. It's free and simple to install on any system that has a RDBMS such as mysql. I use www.supanames.co.uk (http://www.supanames.co.uk) who charged me 50+ UKP for the service for 2 years including my own domain name.

Check out phpbb.

Thanks Wudang!

Yes, phpbb would be quite nice as the discussion board, but then I would need some other software for the wiki-functionality, and again some other for the file mgmt, and I'm afraid that the administration needed to keep all three tools running and configured would be prohibiting. Not that I couldn't find the skills to do it, just to have someone in the organization spending time administrating several tools.

I'd like to find an integrated piece of software that helps me out.

Two more I have found so far is:

http://www.centraldesktop.com/
and
http://www.socialtext.com/


Anyone with experience from either of these?

I can't speak about hosted services, because I've never really looked into them. But if you're willing to host it yourself, Drupal (http://drupal.org) and Civic Space (http://civicspacelabs.org/home/) (a repackaged version of Drupal) have all the features you listed and are widely used, well-regarded, and free.

Thankx PixyMisa, looks interesting! There seems to be hosted versions available also, I'll look into it!
